Maxine-MACHINE.

Specilieation iorniiug,v part of Letters latenl No. 43,7541, dated Angiisl 9. i364.

To all whom it may concern:

Be it known that I, Il. Y. lSEL1iiNG,of 0ppeiiheini, in the county of Fulton and Sta-te of New York, have invented anew and Improved Machine for Milking Cows; and 1 do hereby declare that the following is a full, clear, and, exact description thereof, which will enable any person skilled in the art to make and use the same, reference being had to the accompanying drawings, making a part ef this speci lication, iu which- Figure 1 is a side Vsectional elevation ol' my invention. Fig. 2 is an end sectional elevation of the same. Fig. 3 is a plan view of the same.

Similar letters of reference indica-te like part-s.

This machine is intended to act upon the tea'ts of the cow or animal to be niilked niueh in the same ina-nner as the liniiian hand acts iii the operation of in iiking-that is to say, the machine presses the teat iirst at the neck or upper part, then upon the bodythereof, and then upon its lower part.

I provide a suitable rectangular frame, A, made as shown or in any forni which the skill ot' the maker may suggest. I ii lthis frame I mount a 'driving crank-shaft, li, and pinion U, which latter gears with a piiiiou, l), on the lower end of the vertical shaft E. By turning v the crank-shaft B motion is imparted to shaft.

E. This shaft has attached to it a pair of blades or wings, F, arranged as shown.

Within' the frame A, upon each side ol' the shaft E, there is a loose flat plate or presser, G G', which are connected together at top and bottom by springs 1I H, of rubber or other material. These springs serve to draw the. pressers Gr G' toward each other, and they thus press or clasp the wings F F between them. By the rotation of the wings their sides and edges are alternately presented against the sides of the pressers, which latter are thus alternately driven apart by the edges of the wings and' then drawn by the springs ll toward the sides of the rings. The pressers G ,(i' are thus made to open and close by the rotation of the shaft E.

It is to be particularly observed that the inclined position of the wings F F causes the upper corner 'of each win g to strike first against theupper partof the presser, pushing its upper part over into the inclined position shown in red, Fig. 2, and then, as the wing advances, allowing the presser to assume a perpendieul lar position tilLthe lower corner of tliewing begins to act on the corner part of' the'presser, by which the. lower part of the presser is thrown or pressed ont while the upper part thereof falls in, vas shown in Fig.4 u. The piessers G G' thus have a wabbling niet-ion, while at the same time they advance and recede horizontally.

Opposite to the face of each of the pressers G G' is an adjust-able plate, L L', toward which the pressers act, and the. cow or animal is niilked by having hei teats introduced between the plates L L' aiul the pressers G G', as indicated bythe red lines, Figs. 1 and 2. The plates L L' are adjusted to or from the the prcsseis G (i bv means of the horizontal screw-rods I I, which have ascrew-thread at each end, which enters a corresponding nut in each end ofthe plates L L'. At the center oi" each screw-rod l there is a linger-spoke, J, by which the rods l l are turned and the plates L L' adjusted at pleasure. The object ot' this adjustment is to permit the convenient-regulation of the degree ol' pressure imparted to the aninials teats, and also to adjust the machine to teats ot' dll'erent sizes. 'llie nea-rer the plates l'i L' are brought toward the wings .F of course the greater will be `the pressure npoii the teats of the animal, while. the pressnre will be less when the pla-tes are adjusted outward. The screw-rods [pass through the pressers (l (l', the lat ter being perforated for that purpose. The rods] thus serve in Sonie degree to guide the pressers tr G', at the saine time allowing them to have the'wabbling motion before spoken ol'. 'Phe edges of the frame, as shown at ay o, also assist in guiding the pressers G G' and preventing them from becoming displaced.

The pressers, instead ol' being 'connecteih' may have independent springs. Instead ol' one presser to act upon each pair of teats, there may be a separate presser for each tea-t. Under the pressers ,l arrange a pan, K, which receives the milk and conducts it tlirongli pipe J' to a pail, trough, or othefsuitable receptacle.

This machine is intended to he attached to an arni or bar ot' a suitable stool or support, ot' such forni that when applied under the cows bag to the teats the crank will be in convenient position for the operator. Theaction of the pressers is rst to squeeze the neck of the teat, then 'press downward upon the body thereof, and finally squeeze the lower part, the whole movement or action being substantially thevsame as the `operation of hand-milking. v v

I iind in practice that the best proportion for the speed of the winged shaft is to have its pinion-wheel so made that said shaft will have six and a half revolutions -to each revolution of the crank-shaft. The time and power expended in producing this revolution is about the same as that requiredto press a a single teat once with the hand i'n the common manner.

I do not limit myself to the precise forni,l construction, or arrangement of the parts ot:

. the machine, for they may be varied at will.

Having thus -described my invention, Iclaim as new and desire to secure by Letters Patent- 1. The use of one or more pressers, G G',

acting substantially vin the marmer and for 4the purpose herein shown and described.

2. The combination of lthe plates L L' with the pressers G G', substantially as herein shown and described, for the plu'pose set forth. .3. The combination of the winged shaft E with the pressers G G', substantially in the manner and for the purpose herein shown and described.

4. TheI springs HH, in combination with the pressers G G', substantially as herein setforth.

.5. The ndjnstngscrew-rods I, i'n combination with the plates L L', substantial] y-as and for the purpose herein shown and described.

6. The, arrangement of the pan K' with the pressers G G' and plates L L', as herein shown
